<P>PROBLEM TO BE SOLVED: To improve the performance of a device for supplying liquefied gas fuel to an on-vehicle fuel tank of an automobile by changing a plurality of fuel storage containers, and to control any increase of the filling work time by changing the fuel storage containers. <P>SOLUTION: A supply device of liquefied gas fuel for an automobile includes: a plurality of fuel supply pipes 9a, b for supplying liquefied gas fuel in a liquid phase in a plurality of fuel storage containers 3a, b to an on-vehicle fuel tank; a plurality of pressurizing gas pipes 21a, b which are communicated with a pressurizing gas container 5 to supply pressurized gas to a vapor phase part of each fuel storage containers; and a control means 49 which controls the opening/closing operation of each fuel supply valves 13a, b provided in the fuel supply pipes, and pressurizing valves 27a, b provided in the pressurizing gas pipes. When the amount of liquefied gas fuel in a fuel storage container is reduced ≤20% of the maximum storage amount, a control means opens a pressurizing valve of another fuel storage container after the elapse of the set time before the filling work in an on-vehicle fuel tank is completed, and then, closes a fuel supply valve of the fuel storage container presently under filling operation, and opens a valve of another fuel storage container. <P>COPYRIGHT: (C)2013,JPO&INPIT |
